# Install Nightfall AI Extension via a Common MDM Profile

This walkthrough adds Nightfall extension settings to an existing custom macOS profile when that profile already manages the browser.

When another profile already controls a browser's `ExtensionSettings`, macOS does not merge that key across profiles. Add the Nightfall extension inside the profile that already owns the browser. A second profile that also sets `ExtensionSettings` for the same browser overwrites one of the two.

Safari is not configured this way. Deploy the signed package described in [Deploy the Nightfall Safari Extension with MDM](/data-exfiltration-prevention/exfiltration_endpoint/additional-methods-to-install-nightfall-ai-extension/deploy-the-nightfall-safari-extension-with-mdm.md).

## Google Chrome and Chrome Beta

Add these dictionaries inside the profile's `PayloadContent` array.

```xml
<dict>
	<key>ExtensionSettings</key>
	<dict>
		<key>jgmgecncmjklkabkejnjfgfkglapfgek</key>
		<dict>
			<key>installation_mode</key>
			<string>force_installed</string>
			<key>update_url</key>
			<string>https://clients2.google.com/service/update2/crx</string>
		</dict>
	</dict>
	<key>PayloadDisplayName</key>
	<string>Google Chrome - Nightfall Extension</string>
	<key>PayloadIdentifier</key>
	<string>com.google.Chrome.8370900F-6579-4703-8FEF-1DE3DD384618</string>

	<key>PayloadUUID</key>
	<string>8370900F-6579-4703-8FEF-1DE3DD384618</string>
	<key>PayloadVersion</key>

	<string>com.google.Chrome.beta</string>
	<key>PayloadUUID</key>
	<string>A6E44352-4604-4968-8F35-F74BA0FE5C48</string>
	<key>PayloadVersion</key>
	<integer>1</integer>
</dict>
```

## Other Chromium browsers

Edge, Brave, Arc, Vivaldi, Comet, and Atlas use the same extension ID as Chrome: `jgmgecncmjklkabkejnjfgfkglapfgek`. Set `installation_mode` to `force_installed` and `update_url` to `https://clients2.google.com/service/update2/crx` inside the payload you already use for that browser.

## Firefox

If another profile already sets Firefox `ExtensionSettings`, add the `firefox-addon@nightfall.ai` entry inside that payload. Otherwise add this dictionary to `PayloadContent`:

```xml
<dict>
	<key>EnterprisePoliciesEnabled</key>
	<true/>
	<key>ExtensionSettings</key>
	<dict>
		<key>firefox-addon@nightfall.ai</key>
		<dict>
			<key>installation_mode</key>
			<string>force_installed</string>
			<key>install_url</key>
			<string>https://addons.mozilla.org/firefox/downloads/latest/nightfall-dlp-for-browsers/latest.xpi</string>
		</dict>
	</dict>
	<key>PayloadDisplayName</key>
	<string>Firefox - Nightfall Extension</string>
	<key>PayloadIdentifier</key>
	<string>org.mozilla.firefox.8C56EFE7-402E-4F07-988E-004C44635DBC</string>
	<key>PayloadType</key>
	<string>org.mozilla.firefox</string>
	<key>PayloadUUID</key>
	<string>8C56EFE7-402E-4F07-988E-004C44635DBC</string>
	<key>PayloadVersion</key>
	<integer>1</integer>
</dict>
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.nightfall.ai/data-exfiltration-prevention/exfiltration_endpoint/additional-methods-to-install-nightfall-ai-extension/install-nightfall-ai-extension-via-a-common-mdm-profile.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
